Tuesday, as we reported, Facebook said it was responding to high demand for the shares with an increase in the expected price, to between $34 and $38 per share from the original estimate of $28 to $35.

If the shares sell at the high end of the new range, Facebook would raise about $16 billion.

As we've also reported, though, it's going to be next to impossible for small investors to get their hands on the stock at its initial offering price — and there's word that General Motors is going to stop advertising on the website because it questions the effectiveness of such ads.
